I have long appreciated the thoughtful and challenging work of Nick Rate, no more than in this Slideshare. It is worth going to his blog post for some further questioning thoughts.
Much of what he writes makes for very good pedagogy although he raises several questions which we at eFolio in the UK believe we have the answers. One typical 'error' in my way of thinking, is to consider an e-Portfolio as a tool for Assessment OR a tool for recording Process(es) OR a tool for Showcasing. In eFolio it is quite possible for the one e-Portfolio to be used for all three (and more) functions at the same time. This can be done as soon as one understand the principle of writing for a specific 'Audience'. In eFolio artefacts can be uploaded once and yet repurposed according to the 'view' presented to specific readers.
Again, Nick raises issues of ownership and portability which need to be resolved by each individual school. Unfortunately, he leaves these questions unanswered, and, until they are, schools cannot really start on a track that they might regret later. eFolio has been purposely designed to overcome the questions that Nick leaves unanswered.
Well, apart from my gripes, New Zealand should be very proud of the work of such energetic leaders!
